TELEPHONE.

SPECIFICATION forming part of Letters Patent No. 738,861, dated September 15, 1903. Application filed June 18, 1901. Serial No 65.080. (No model.)

To aZZ whom it may concern.-

Be it known that I, MILTON IRVIN VOUGHT, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of WVisconsin, have invented certain new and useful Improvements in Telephones; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in telephones; and the objects are, first, to provide new and useful means for actuating the driving-gear of the rotating armature of the magneto-generator in the signal mechanism; second, to aggroup and combine with such actuating means the conducting-wires of the telephone, and, third, to aggroup and combine with said means the conducting-wires of the receiver and transmitting circuits, and generally the object is to increase the convenience of manipulating and using the telephone and transmitter. These objects I accomplish by securing the box or casing of the instrument in an elevated position and applying to the generator mechanism an actuating-cable which may be lengthened or shortened relatively to the desired position of the telephone and receiver, whereby the telephone and receiver may be raised and lowered to any desired height and held at such point.

I have fully and clearly illustrated the invention in the accompanying drawings, wherein- Figure 1 is a view inelevation showing the casing as secured to a horizontal surface and the actuating-cable arranged in operative position with the combined receiver and telephone suspended from the lower end of the cable. Fig. 2 is a skeleton view of the easing, showing in end view the pinion of the rotating armature, the driving-gear, and the driving-pulley mounted on the shaft of the driving gear, with the cable arranged in proper relation thereto. Fig. 3 is a side view of the magnote-generator, showing the armaturepinion, the driving-gear, and drivingpulley, with the actuating-cable in operative connection and arrangement. Fig. 4is a de' tail view showing the casing secured to a vertical surface with the cable carried over a bracket-arm. Fig. 5 is a detail view showing the driving pulley and the pawl and ratchet connected therewith.

It will be premised that the respective circuits are substantially identical with those associated with any well-known telephone, except that the receiving and the transmitting wires are grouped at their entrance into the actuating-cable and carried therethrough to the combined receiver and telephone, as indicated in the drawings in Figs. 2 and 3.

Referring to the drawings, Figs. 2 and 3, a designates the magneto-generator of a wellknown type made up of horseshoe-magnets secured in position by the usual means.

Mounted between the legs of the horseshoemagnets adjacent to their poles is the rotative armature 19, carrying on the extended portion of its arbor or axle the small pinion 0, arranged to mesh with the larger gearwheel cl, constituting the driving-gear for the armature. This gear-wheel (Z is mounted 011 a rotatable shaft (1, arranged in the usual supports. The parts and functions, connections, and operation of this magneto-generator being well known in telephonic service and systems it is not deemed necessary to more particularly describe it. It is generally operated by means of a crank attached to the .shaft of the large gear-wheel, and it is one of the purposes of my invention to do away with this crank and substitute other and improved means for actuating the signaling mechanism, and this I accomplish by the following-described instrumentalities: On the end of the shaft of the driving-gear d is loosely mounted a grooved pulley 6, adapted to have arranged thereon the actuating'cable. A ratchet-disk e is fixed to the said shaft to be engaged by a double-acting pawl 6 pivotally secured to the face of the grooved pulley, as shown in the drawings, whereby the pulley is held fast to turn with the shaft in one direction, but is free to turn loose in the other, so that the rotating armature will not be reversed by the return adjustment of the cable.

h designates a flexible cable which surrounds and within which are inclosed the necessary conductors of the transmitter and receiver circuits leading into the cable at its upper end, preferably at a point within the casing, and carried through the cable to their appropriate terminations and connections in the receiver and transmitter in the combined instrument at the lower end of the cable. Thus the circuits of the battery, the induc tion-coill, main lines, &C., and such connections as are essential for the operation of a telephone are connected with the conductors in the flexible cable h. The flexible cable h at the upper end is secured to a point in the casing and extends vertically downward a distance from where it is reversed and arranged in vertical direction and carried over the grooved driving-pulley, and from thence extends depending in Vertical direction and has the combined transmitter and receiver secured to its lower free end. At the end of the loop formed in the cable is arranged a counterweight f, carrying a grooved pulley g, journaled in the weight and carried by the cable;

It will be perceived from the foregoing description, taken in connection with the drawings, that the telephone and receiver are suspended from the cable and their weight counterbalanced by the weight f on the cable within the loop made therein, so that when it is desired to use the telephone the combined transmitter and receiver are pulled down, moving the cable therewith, which movement rotates the armature and energizes the generator, and that raising the telephone and receiver will lower the counterweight without aifecting the circuits of the signal or generator, because the reverse of the loose and fast pulley 0 makes the pulley idle and does not operate the armature, and the telephone is held in any position to which adj usted by the cable. The arrangement allows the user to move the telephone and receiver to the limit permitted by the length and disposition of the cable without breaking the circuits or in any way interfering with the working of the instrument. In lowering the telephone and receiver the cable passing about the driving-pulley e rotates that elephone secured to the free end of the cable, whereby the. armature may be rotated by the extension of the cable.

2. The combination with the rotating armature of the magneto-generator, of a grooved pulley loosely mounted on the shaft of the driving gear thereof, meansv to lock the grooved pulley to the shaft, a cable on the grooved pulley, a counterweight and pulley on the cable, conductors inclosed in the cable, and a telephone secured to the free end of the cable and in circuit with said conductors.

3. The combination with the rotating ar.- mature of the m agneto-generator, of a grooved pulley mounted on the shaft of the drivinggear thereon, a flexible cable to rotate the pulley, conductors within the cable, and a telephone secured to the free-end of the cable and conductors.

4. The combination with the rotating armature of the magneto-generator and the driving-gear thereof, of a grooved pulley on the shaft of the driving-gear, a cable arranged on the pulley, conductors in the cable, a telephone suspended from the free end of the cable, and a weight on the cable to counterbalance the telephone.

5. In a telephonic mechanism, the combination with the ringing mechanism, of a flexible cable to actuate the ringing mechanism, a pulley to carry the cable, a transmitter and receiver secured to the lower end of the cable, conductors in the cable in circuit with the respective lines and the circuits of the transmitter and receiver, and a weight on the cable to counterbalance the transmitter and re- 'ceiver.

6. In a telephonic mechanism, the combiaation with the transmitter and receiver circuits, the combined transmitter and receiver, and a grooved. pulley on the driving -gear of the generatonarmature, of a cable arranged to actuate said pulley, conductors in the cable connecting the circuits and the transmitter and receiver, and a weight on the cable to counterbalance the transmitter and receiver.

'7. A telephonic mechanism comprising a flexibly-supported, adjustable, pendent telephone in which the flexible supports are made up of electric conductors, a pulley to carry the flexible supports, a weight on the supports to counterbalance the telephone, and means whereby the operation of the weight and telephone simultaneously operates a ringing mechanism.

In testimony whereof I affix my signature in presence of two witnesses.
